●A-phase (Signal) Output, B-phase (Signal) Output
Whether the axis rotation is clockwise or counterclockwise is judged with difference of A and B phases by outputting incremental encoder as shown below. The A-phase precedes the B-phase in case of a clockwise rotation (CW).
An encoder with a function to detect the absolute position so that it does not have to return to origin whenever it is powered on.
A position against the reference point (origin). The antonym is “incremental position.”
●Absolute Positioning Repeatability
Difference between the coordinate value and the actual value when positioning at any point indicated by the coordinate value.
●AC Servo Motor
A servo motor rotated by an alternating current in the fixed winding. It does not have a brush and a commutator which are weaknesses of DC servo motors.
An absolute position given in an absolute coordinate system.
A method of transferring indications to actuators. One is absolute addressing (absolute coordinate system), the other is incremental addressing (relative coordinate system, indicating the distance of transfer).
An signal sent when something wrong (trouble) has happened in the device.
An operation activated by a start signal from an external device (PLC etc.)
